astscript-radial-profile1
Create a radial profile of an object in an image
Usage
astscript-radial-profile [OPTION]
FITS-files
Overview
This script is part of GNU Astronomy Utilities 0.23.
This script will consider the input image for constructing the radial profile around a given center with elliptical apertures.
For more information, please run any of the following commands. In particular the first contains a very comprehensive explanation of this script's invocation: expected input(s), output(s), and a full description of all the options.
